Hallow's eve isn't part of UK vernacular, so you'd need to set it up / explain it, bruv (but enough people have been exposed to US culture that they'd get prolly) also, Jon Jon saying something about smoky hollow / lean etc.

I'm drunk enough I assumed battles were on Halloween, but if it's the street name will probably go over well. after Avo and Diz' international pandering discussion please don't wear football / soccer jerseys / shirts folks...unless Ars.
